What information do you have about the relative positions from which the images were taken? What information do you have about the focal length (or any other information that might allow you to calculate distances by parallax) ?

the 6 images are taken from different view this contains
image1=front image
image2=up right image
image3=low right image
image4=back image
image5=low left image
image6=up left image.
And I think we need to use homography concept is that right? What are steps do I need to take to transfer these set of images in to bird eye view. I think we can do geometric transformations.

This capability does not exist built-in in MATLAB, unless you want to write something yourself. There is some information here: http://en.wikipedia.org/wiki/Homography
Perhaps you'll need to use Autodesk, which can do what you're asking for: http://www.123dapp.com/catch Watch their video. It's quite impressive. It would take you and all your friends years to make something not even as good as that in MATLAB, so why bother when you can just buy 123D Catch?

i dont think that this would be good approach for now because this is academic project thats why i want to manually implement these things.

Then you should have labeled it as "homework" - I'll do this now for you. Since you have to do it yourself, you should use the formulas your professor went over in class, or get help from him with the concepts listed in the Wikipedia article I gave you. I don't have any code to give you on that subject. By the way, you should review some of your old posts and accept answers from people who have helped you.
